I'm really satisfied with the UniTak3D PEI Build Plate for Bamboo Lab A1 Mini! The quality of the finish is excellent - the double surface (smooth/textured) provides perfect adhesion for different types of filaments. The flexibility of the steel sheet with PEI makes the removal of printed parts much easier and effortless. The compatibility with the Bambu Lab A1 Mini printer is perfect, and the product fits without adjustments. I recommend it to those who want to improve the printing experience with more consistency and more professional results!

My Bambu X1C came with only one PEI texture plate and I wanted a second one to enable rapid turnaround. This works and I'm happy with it even with a tiny issue. It lacks the Bambu coding on the front edge that identifies the plate to the printer during start up. My printer pauses and asks me to verify the plate is in and aligned on the bed plate. I just have to confirm and press continue for it to go on. A bonus is the back side is smooth so a print on the reverse side is smooth on the print. I don't mind the texture look but it's nice to have a smooth option. Use a glue stick on the smooth side per Bambu to ensure it sticks and comes off when you need it to.

Color: Double Sided PEI (Smooth+Textured)

I really wanted to like the UniTak3D PEI build plate for the Kobra S1, but after only two months of normal use, it has become completely unusable. The smooth PEI side developed bubbles beneath the surface, creating raised spots that ruin first-layer consistency. These are not minor defects—they make reliable printing impossible. Unfortunately, the textured side isn’t a usable fallback. It is not level with the build plate frame, so it also produces inconsistent first layers. Between the bubbling on one side and the uneven surface on the other, the entire plate is effectively unusable. I’ve gone through normal cleaning and troubleshooting steps, and this is clearly a manufacturing or material failure—not user error. A build plate should last significantly longer than two months, especially under standard printing conditions. This is a core component of the printer, and durability matters. Failing this quickly raises serious concerns about quality control. At this point, I cannot recommend this product. It simply doesn’t meet basic expectations for longevity or reliability.

Perfect for PETG/PETG CF. I don't like using glue on the printer bed unless it's absolutely necessary, like when using TPU or TPU AIR. PETG doesn't stick at all to the stock plate that comes with the A1 Mini, but no issues whatsoever with this new one. Good to have extras anyway.

Performs as it should, however, the ad is extremely MISLEADING. It appears as though there are (2) plates included in the sale. There is only (1) plate.

This PEI plate is a significant infrastructure upgrade for my Bambu Lab a1 3d Printer. The 257x257mm fit is perfect, and the magnetic "snap" is secure, ensuring zero shifting during high-acceleration moves. Prints stick perfectly at standard temperatures and practically "pop" off on their own once the plate cools down. The texture leaves a professional, matte finish on the bottom of parts, which is a major aesthetic win for any graphic design or modeling project.

I used the UniTak3D Kobra S1 PEI Build Plate 264x276mm pretty heavily, and unfortunately it didn’t hold up as well as I hoped. Pros: Works well at first Dual-sided surface is nice in theory Fits properly and installs easily Cons: Wore out after about a month of heavy use Started showing ghosting issues over time Didn’t last as long as other plates I’ve used In use, it performed fine early on, but after consistent printing it degraded quicker than expected. Toward the end, I started noticing ghosting and reduced print quality, which led me to replace it sooner than I would have liked. Overall: It’s decent at first, but durability was a letdown for me. If you print a lot, you may want to consider other options that hold up longer.
